So God created man in his own image, in the image of God he created him; male and female he created them.' (Genesis 1:26-27 the Holy Bible New International Version - NIV).
Christians who seek to argue against abortion on the basis of Scripture (the Bible) use a number of verses that seem to teach that God knows and plans the life of a person before they are born. In the Psalms David wrote:.
'For you created my inmost being; you knit me together in my mother's womb. I praise you that I am fearfully and wonderfully made; your works are wonderful, I know that full well. My frame was not hidden from you when I was made in the secret place. When I was woven together in the depths of the earth, your eyes saw my unformed body. All the days ordained for me were written in your book before one of them came to be' (Psalm 139:13-16 NIV).
The Prophet Jeremiah spoke similar words: 'The Word of the Lord came to me, saying, "Before I formed you in the womb I knew you' (Jeremiah 1:5 NIV). Even Mary was told by the angel Gabriel that God had a plan for the baby (Jesus) she was going to have ('He will be great and will be called Son of the Most High' (Luke 1:32 NIV)) and John 'leapt in the womb' when Mary came to visit Elizabeth (his mother - Luke 1:41). From this it is argued that God knows each human and has a plan for each of us that is shaped and formed in the mind of God even before we are born. Human life begins at conception so abortion is wrong.
The strongest biblical evidence used against abortion is the prohibition to commit murder (Exodus 20:13). Christians against abortion believe the embryo/foetus is human and should be give full human rights. Anyone taking away its life is committing a grievous act of disobedience against God (they are committing murder) and are putting themselves on a level with God who alone gives life and takes it away.
